First, I took my custom English lyrics and processed them into Unicode characters, which were then encoded into raw UTF8 byte values (0–255). Next, I applied Frequency Shift Keying (FSK) to map each byte directly to a distinct audio frequency, converting the text data into a continuous synth signal. This raw digital stream served as the foundational rhythmic and melodic texture for the entire composition. The result is a fusion of decentralized code and cyberpunk soundscapes, turning the message of Bitcoin directly into audio.\",\"playlist_name\":\"Whisper of BTC\",\"is_private\":false,\"playlist_image_sizes_multihash\":\"baeaaaiqsecw6wqvnmfwjw4xqv5i53deneuquhcjmagu6kewnsgygbnzgb3kl2\",\"release_date\":\"2026-08-15T21:22:16.000Z\",\"ddex_release_ids\":null,\"ddex_app\":\"\",\"upc\":\"\",\"artists\":null,\"copyright_line\":null,\"producer_copyright_line\":null,\"is_image_autogenerated\":false,\"playlist_contents\":[{\"timestamp\":0,\"metadata_timestamp\":1786829033,\"track_id\":660155223},{\"timestamp\":0,\"metadata_timestamp\":1786830488,\"track_id\":1348136656},{\"timestamp\":0,\"metadata_timestamp\":1786834613,\"track_id\":1211799308},{\"timestamp\":0,\"metadata_timestamp\":1786881847,\"track_id\":295565371}]}}",
